County committee debates wide-ranging changes to development impact taxes; votes deferred while staff, schools and finance seek more analysis

The Montgomery County Government Operations and Fiscal Policy Committee spent its Oct. 10 session reviewing Bill 16-24, a broad package of proposed changes to the county’s development impact taxes for schools and transportation. The meeting combined presentations from planning and fiscal staff, testimony from Montgomery County Public Schools and planning board leadership, and extensive councilmember debate about trade-offs between affordability, adequacy and fiscal stability.

Council staff opened with a framing of impact taxes: those revenues are a function of the tax rate and the amount of development, and are therefore volatile. "The fiscal impact statement from OMB estimated a negative fiscal impact of $28,000,000," council staff reported when summarizing the packet’s fiscal analysis, while noting some of the reduction relates to the LATR program spread over multiple years.

A central technical recommendation from the planning board — and the meeting’s primary dispute — would adjust how school impact tax rates are calculated by removing from the county’s per-seat cost the portion already covered by state aid. Planning director Jason Sartore showed analyses indicating school construction costs rose sharply between FY22 and FY24 and that an increased share of those costs were covered by state funds. "The board's recommendation sets the school impact tax rate...to what the county actually pays for school capacity improvements," Sartore said, arguing the change would better align what developers pay with the county’s net cost.

Montgomery County Public Schools opposed the proposal. "MCPS is very concerned about this provision," said Essey McGuire, chief of staff for MCPS, noting state aid eligibility is assessed project-by-project and warning that excluding state aid could create unintended consequences for the county’s relationship with the state. OMB fiscal staff, Rachel Silberman, cautioned that recent school-construction cost spikes were driven in part by a temporary surge in state funding (the "Built to Learn" program) and that permanently adjusting the tax base could reduce revenues while the county still needs heavily programmed school projects in its six-year CIP.

Council members largely agreed the issue requires more analysis. Several members noted that the county’s cap-and-carryover rule will drive a 20% increase in school impact rates at the next update and that a deliberate, data-driven review is warranted. The committee instructed staff to return on Oct. 17 with targeted follow-up materials and—separately—to draft a council resolution to convene a working group or task force to study the suite of policy questions that cut across impact taxes, adequacy standards, equity and funding mechanisms.

Other recommendations in the packet drew mixed responses and similar requests for follow-up. The committee agreed to continue the recently adopted cap-and-carryover mechanism to smooth future increases and to maintain a transportation exemption for bioscience projects; it held off votes on several proposed discounts and exemptions (including a 50% discount for small single-family units, multifamily 3+ bedroom exemptions, and office-to-residential conversion rules) pending additional analysis. Planning presented new student-generation data for townhomes and multifamily unit sizes; staff recommended deeper study of student generation by unit type before adopting size-based discounts.

Developers requested an extension to the expiration of certified transportation impact tax credits for some multi-year projects; MCDOT and council staff reported a small number of pipeline projects would be affected, and the committee moved to support extending certain credit certification periods for projects meeting specified criteria.

What’s next: The committee scheduled a follow-up work session on Oct. 17 to consider technical amendments and to vote where members feel adequately informed. Council staff will draft a resolution to form the proposed task force and will return with more detailed fiscal and project-level analyses, student generation breakdowns by unit size, and listings of pipeline projects affected by opportunity-zone and policy-area changes.
